FEED-GRINDER.

Specification of Letters Patent.

Patented June 1, 1915.

Application filed November 26, 1913. Serial No. 803,312.

To all whom it may concern:

Be it known that I, Lnoxnms PE'llIO UD, a citizen of the l nited States, residing at Beatrice. in. the county of Gage and State of Nebraska, have invented new and useful Im n'ovements in Feed-Grinders, of which the following is a specification.

This invention relates to feed grinders and it consists in the novel features hereinafter described and claimed.

An object of the. invention is to provide a grinder of simple structural arrai'ig'ement which is adapted to efiiciently reduce feed as for instant". alfalfa, hay, corn, wheat, oats and the like to small particles in order that the same may e prepared for stock feeding.

\Vith the above object in view the grinder comprises a shaft from which is mounted a series of spaced saws. Bars are mounted on av fixed support and project into the spaces between the saws the said bars are approXi-.

mately radially disposed with relation to the saws. A plate positioned adj aeent the saws and is disposed at a tangent to a circle struck from the center of the saws and the said plate is provided with teeth which project into the spaces between the saws. A bar is mounted under the said plate and eX- tends transversely across the saws in close proximity to the ends of the teeth thereof. The said bars and plate are of hard steel and ma y he mounted on suitable supports of any desired material.

In the accr'nnpanying drawings: Figure 1 a side elevation of the grinder. Fig. 2 is a top plan view of the same. Fig. 3 is a Fig. l is a perspective view of a plate used upon the grinder. Fig. 5 is a perspective View of a tooth used upon the grinder. Fig. 6 is a side elevation of a modified form of arrangement of the parts o the grinder.

As illustrated iri the drawing the grinder comprises a frame 1 upon which is journaled a. shaft 2-. Any suitable means may be provided for rotating the shaft. Saws 3 are keyed upon the shaft 2 and are held in spaced relation with espect to each other by means of disks 4 which are interposed between the saws and which are also keyed upon the shaft.

in close contact with the sides of the disks throughoutthe series of saws and disks.

Bars 5 of hard steel are mounted upon the framel at one side of the series of saws and the said bars are provided with pointed ends The sides of the saws are G which project into the spaces between the saws and which terminate in close proximity to the peripheries of the disl s 4-. A block 7 is mounted over the bars 5 and a plate.- 8 is attached to the said block. The saidplate ties ina plane which is disposed at a tangent to a circlestruclc from the. centers of the saws. The plate 8 is provided at its lower edge with teeth 9 which project into the spaces between the saws. The said plate is made from. hard steel. A bar 10 is attached to the block 7 and lies under the lower por tion of the plate 8 and teeth 9 thereof. The said bar is also of horn steel and extends transversely across the series of saws 3 and its inner surface is in close proximity to the ends of the teeth of the said saws. A hopper 11 of any desired form may he positioned upon the frame 1 over the upper portions of the saws and the block 7 and plate 8.

The material to be ground is deposited on thehopper l1 and the shaft 2 is rotated. Thus the teeth. of the saws touch the said material and carry it toward the plate 8. Atthe edges of the teeth 9 of the said plate the saidmaterial is cut into bits which may be as large or smaller than the spaces between the adjacent teeth of the saws 3. This cut material is carried down by the teeth of the saws and when the teeth are below the centers of the saws the said material falls from the teeth into any suitable receptacle provided for its reception.- Therefore it will he seen that a grinder of simple structure is provided for reducing feed material to small particles. f desired the plate 8 and block '7 may be dispensed with and in this instance a second set of bars 5 is positioned adjacent the opposite sides of the saws from the first mentioned set of bars and the last mentioned setof bars will direct the material onto the saws and will remove any particles of the material from between the saws which may be carried around the saws from the first mentioned set of bars.

Having described the invention what is claimed is A grinder comprising a frame, a shaft journaled upon the frame, a set of saws fixed to the shaft, :1 set of disks fixed to the shaft. and interposed between the saws and maintaining the saws in spaced relation, a set of bars fixed to the frame and having end portions which project into the spaces between the saws and which terminate in close proximity to the peripheries of the above the bars, a plate mounted upon the block and having at its lower-edge teeth which project into the spaces between thebars and which rest against the upper edges of the said bars the said plate being disposed at a tangent to a circle struck from the center of the saws and the upper surfaces of the teeth disposed at an angle to the upper surface of the body of the plate, and a bar mounted upon the block beneath the plate and the teeth thereof and having a surface in close proximity to the ends of the saws and which bridges the spaces between the teeth of the plate, the lower edge 15 of the last mentioned her resting upon the upper edges of the first mentioned bars.

In testimony whereof I afiix my signature in presence of twowitnesses.
